DragRigidbody by clicking anywhere

Hi,

I'm using the DragRigidbody script to move my character around. I understand that it is as if there is a spring with one end attached to my cursor and the other end attached to the player.

Code (csharp):

1.  
2. var spring = 50.0;
3. var damper = 5.0;
4. var drag = 10.0;
5. var angularDrag = 5.0;
6. var distance = 0.2;
7. var DistanceOfObject = 1;
8. var attachToCenterOfMass = false;
9. var Enabled : boolean;
10. private var springJoint : SpringJoint;
11.  
12. function Update ()
13. {
14.    
15.     // Make sure the user pressed the mouse down
16.     if (!Input.GetMouseButtonDown (0))
17.        
18.     return;
19.    
20.     var mainCamera = FindCamera();
21.    
22.     // We need to actually hit an object
23.     var hit : RaycastHit;
24.     if (!Physics.Raycast(mainCamera.ScreenPointToRay(Input.mousePosition),  hit, DistanceOfObject))
25.     return;
26.     // We need to hit a rigidbody that is not kinematic
27.     if (!hit.rigidbody || hit.rigidbody.isKinematic)
28.     return;
29.    
30.     if (!springJoint)
31.     {
32.         var go = new GameObject("Rigidbody dragger");
33.         var body : Rigidbody = go.AddComponent ("Rigidbody") as Rigidbody;
34.         springJoint = go.AddComponent ("SpringJoint");
35.         body.isKinematic = true;
36.     }
37.    
38.     springJoint.transform.position = hit.point;
39.     if (attachToCenterOfMass)
40.     {
41.         var anchor = transform.TransformDirection(hit.rigidbody.centerOfMass) + hit.rigidbody.transform.position;
42.         anchor = springJoint.transform.InverseTransformPoint(anchor);
43.         springJoint.anchor = anchor;
44.     }
45.     else
46.     {
47.         springJoint.anchor = Vector3.zero;
48.     }
49.    
50.     springJoint.spring = spring;
51.     springJoint.damper = damper;
52.     springJoint.maxDistance = distance;
53.     springJoint.connectedBody = hit.rigidbody;
54.    
55.     StartCoroutine ("DragObject", hit.distance);
56. }
57.  
58. function DragObject (distance : float)
59. {
60.     var oldDrag = springJoint.connectedBody.drag;
61.     var oldAngularDrag = springJoint.connectedBody.angularDrag;
62.     springJoint.connectedBody.drag = drag;
63.     springJoint.connectedBody.angularDrag = angularDrag;
64.     var mainCamera = FindCamera();
65.     while (Input.GetMouseButton (0))
66.     {
67.         var ray = mainCamera.ScreenPointToRay (Input.mousePosition);
68.         springJoint.transform.position = ray.GetPoint(distance);
69.         yield;
70.     }
71.     if (springJoint.connectedBody)
72.     {
73.         springJoint.connectedBody.drag = oldDrag;
74.         springJoint.connectedBody.angularDrag = oldAngularDrag *2;
75.         springJoint.connectedBody = null;
76.     }
77. }
78.  
79. function FindCamera ()
80. {
81.     if (camera)
82.     return camera;
83.     else
84.     return Camera.main;
85. }
86.  

But I want there to be one difference, I want to be able to click anywhere on the screen and the player end of the string to always attach to a specific point on the player.

I hope I make sense. Does anybody have an idea for how I can do this?

Thank you,
Stuart
